1. hi G&Gs, please remember this organisation chart.

2. landing gear, downlock actuator when does it being pressurized?
--> G&Gs if being ask this questions, we should just answer it is always being pressurised when hydraulic pressure is available. just that the pressure of the hydraulic is being port to either extend side or retract side.

3. there isn't any recirculation fans for 744 freighter a/c. For, 744 freighter, we have extra small small components below. (if missed out, G&Gs can add on)
a. 2 SMACCS/ dump valves for pack 1 and 3
b. Lower forward cargo overboard valve.
c. flight deck ventilation fan
d. main deck fire shutoff valves (if not wrong is 5)
e. lower cargo aircond flow regulating valve and trim air valves.(pack 3 for forward cargo, pack 2 for aft cargo)
f. no fire bottle for main deck cargo. it utilize DEPRESSURIZATION to extinguish fire
g. Humidifier is at the top of the fuselage. not at the L/H lower forward cargo.
